Choose these metric screws for fastening most machinery and equipment. They are twice as strong as low-strength steel screws.

These screws are made to stringent Army-Navy specifications that ensure performance and reliability. They're comparable in strength to Grade 5 steel screws.

These screws are made to Japanese Industrial Standards. They are suitable for fastening most machinery and equipment.

Made from Grade 8 steel, these screws can be used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are at least 25% stronger than medium-strength steel screws.

Choose these screws for their adherence to strict military standards for material and construction. Their high tensile strength means they can be used in demanding, high-stress applications.

These screws come with a traceable lot number and a physical and chemical test report. Use them for high-strength fastening.

These screws are the strongest we offer. They are about 20% stronger than high-strength steel screws and are often used in heavy duty applications such as stamping and earth-moving equipment.

About half as strong as medium-strength steel screws, these screws can be used for light duty fastening applications, such as securing access panels.

50% stronger than our medium-strength steel heavy hex head screws, these screws meet ASTM A490 specifications for structural applications. Use them in joints that require more tensile strength than ASTM A325 screws.

These Grade B7 steel screws are nearly twice as strong as our stainless steel screws for high-pressure applications. Also known as pressure bolts, they meet the high-pressure, high-temperature regulations of ASTM A193 and are used to secure pressure tanks, valves, and flanges.

These metric screws are at least 25% stronger than medium-strength steel screws. Use them in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. The flange distributes pressure where the screw meets the surface, so there's no need for a washer.

Choose these metric screws for fastening most machinery and equipment. With a flange distributing pressure where the screw meets the surface, there is no need for a separate washer.

Comparable in strength to Grade 9 screws, these are about 20% stronger than high-strength steel screws and often used in heavy duty applications, such as stamping and earth-moving equipment. The flange eliminates the need for a washer.

About 20% stronger than medium-strength steel screws, these Grade 8 steel screws can be used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. Serrations under the flange provide mild vibration resistance.

These metric screws are suitable for fastening most machinery and equipment. They have a serrated flange that helps prevent loosening from vibration.

These screws are made from zinc-plated Grade 5 steel that’s stronger than stainless steel and provides corrosion resistance in wet environments. When wired together, they resist vibration better than any other hex head screw.

Place a cotter pin through the hole in the shank to keep a nut from loosening. These screws have a stronger hold than screws with thread lockers or lock washers.

Made from Grade 8 steel, these screws can be used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are more than twice as strong as our stainless steel thread-locking screws. The thread locker helps resist loosening from vibration.

These screws are specially tempered to meet ASTM A193 specifications for temperatures up to 1100° F.

Choose these screws for their adherence to strict military standards for material and construction.

Made of alloy steel, these low-profile screws are nearly twice as strong as their stainless steel counterparts. With half the height of a standard socket head, these low-profile screws fit in tight spaces.

A freely rotating but permanently attached washer distributes pressure over a wider area than a flange, preventing damage to your material's surface.

With a tensile strength of 170,000 psi, these alloy steel screws are among the strongest we carry. They are stronger than Grade 8 steel screws and are nearly two and a half times stronger than stainless steel thread-locking screws. They have a thread locker to prevent loosening from vibration.

Serrations under the head grip the material's surface for mild vibration resistance. The flange distributes pressure across the material's surface, eliminating the need for a washer.

With a tensile strength of 170,000 psi, these alloy steel screws are among the strongest we carry. They are stronger than Grade 8 steel screws and are more than twice as strong as stainless steel wire-lockable screws. These resist vibration better than any other socket head screw.

A zinc plating provides mild corrosion resistance.

A zinc plating on these metric steel screws provides mild corrosion resistance.

Angled under the head, these metric screws fit in countersunk holes and sit flush with the surface of your part.

Also known as wall plate screws, these screws are painted to match the color of a switch or outlet cover.

Made from alloy steel, these screws are twice as strong as standard steel Torx flat head screws.

Made from alloy steel, these screws are nearly twice as strong as stainless steel flat head screws.

These metric alloy steel screws are nearly twice as strong as stainless steel button head screws.
